MEANS FOR SUSPENDING BOBBINS IN CREELS Filed Dec. 1, 1949 Patented May 22, 1951 MEANS FOR SUSPENDING BOBBINS IN CREELS John Kenneford, Accrington, England, assignor of one-half to Howard and Bullough Limited,

Accrington, England Application December 1, 1949, Serial No. 130,552 In Great Britain February 3, 1949 8 Claims. v (Cl.242130) The invention is concerned with the means employed for the suspension of bobbins in the creels of textile machines and in analogous situations, such means being of the known type in which a bobbin is arranged to depend upon an attachment capable of rotating upon and swinging freely about an underhung pivot fixed to the creel or the like, and in which, by a relative axial movement of the bobbin on the shank of said attachment a catch incorporated in the latter is caused to engage with, or be disengaged from, an internal shoulder or other projecting part of the bobbin; the arrangement of a suspen sory attachment of this type is such that a bobbin can readily be secured to the attachment by raising it to pass over the free lower extremity of the attachment and pushing it upwardly until the catch is automatically operated to retain the bobbin in the suspended position, a successive similar upward movement of the bobbin relative to the attachment serving to disengage the catch and free the bobbin for removal.

With the object of providing an improved construction of bobbin supporting means of the said type, the present invention provides inoperative relationship to the catch, a lever capable of movement to turn the catch from the bobbin-retaining position to the inoperative position, and vice versa, and a pivoted tumbler member adapted to be impinged upon by the bobbin when the latter is moved upwardly on the attachment above the position in which it is ordinarily retained, said tumbler member reacting when so impinged upon to actuate the said lever by the gravitational effect of the tumbler with respect to its pivot so as to engage or release the bobbin from the attachment.

The tumbler member is conveniently a weighted rotatable disc mounted eccentrically and having a connection with the catch-operating lever such that, when impinged upon by the bobbin, the disc tumbles over its eccentric axis and thereby throws the catch-operating lever to rotate the catch.

The manner in which the invention may be carried into effect is hereinafter more fully described with reference to the accompanying drawings. In said drawings, Fig. 1 is a perspective view of a bobbin-suspensory attachment as seen when depending from the usual creel of a spinning or like machine, the position of a. suspended bobbin being indicated in dotted lines. Fig. 2 is a vertical section through the attachment and bobbin shown in Fig. 1; and Figs. 3 and 4 are similar views to Fig. 2, respectively illustrating the positions of the parts when the bobbin is raised to actuate the mechanism to release the same, and when the bobbin is ofiered to the shank of the attachment preparatory to its being engaged thereon.

It will be seen from the drawings that the attachment consists of a length of strip metal bent upon itself at its mid-point so as to form a loop II! at one end and a pair of limbs II, I2 which together constitute a shank upon or between which are mounted the several parts of the device as hereinafter described. The strip is pierced at the centre of the loop ID by a hole I3 through which passes the swivel H of a connection to the creel, said swivel preferably incorporating a ball-bearing or other anti-friction bearing I5, the attachment being free to rotate or swing laterally from its mounting on the creel (not shown). The limbs II, I2 of the attachment are secured together in spaced relationship, primarily by the rivet I6 and distance-piece I1, and the shank formed thereby is of a thickness capable of being inserted loosely within the hollow interior of a bobbin I8.

At a point near to the lower extremity of the shank, upon a pin I9 extending between the limbs II, I2, is a pivotal catch or detent 26 made from a plate of substantially lozenge shape. The catch 20 can rotate on said pin I9 between a position in which its major axis is disposed horizontally as shown in Figs. 1 and 2 and a position in which the apices 2|, 22 of the plate at the ends of the major axis have been sufiiciently withdrawn between the shank limb-s I I, I2 to permit the latter to enter the hollow bore of the bobbin I8, as shown in Fig. 3. When turned into the firstmentioned position, in which the major axis is horizontal, the apices 2I, 22 of the plate 28 will engage beneath the interior shoulder 23 formed at the upper end of the bore of the bobbin It and thereby prevent the latter from being removed from the attachment.

A toggle lever 24, mounted on a pivot pin 25 at an intermediate point in its length between the shank limbs I I, I2, is linked at its lower extremity with a pivot 26 on said catch-plate 20 and at its upper end said lever 24 is connected with a tumbler consisting of a weighted disc 2! pivoted upon the eccentric pin 28 in such fashion that it can rock over the axis of said pin 28 from side to side and, when so rocked, its action due to gravity will actuate the toggle lever 24 to rotate the catch-plate 20.

A tapered collar 29, slidable over the shanklimbs II, I2, is arranged so as to be raised by the upper end of the bobbin I8 when this is pushed on to the shank from below, and said collar 29 forms an abutment through which the bobbin can impinge against said weighted disc 21. It will be understood that the disc 21 hangs to one side or other of its pivot mounting 28; when impinged upon by said collar 29 on an upward thrust of a bobbin l8 as aforesaid, the disc 21 is caused to rock or tumble over the axis of the pin 28 to effect the rotation of the catch-plate 20, either into the bobbin-retaining position shown in Figs. 1 and 2, in case it is desired to suspend the bobbin from the attachment, or into the bobbin-released position shown in Fig. 3 should it be required to remove an empty bobbin for replacement by a full one. The collar 29 is prevented from sliding ofi the end of the shank by the projecting ends of the rivet [6". The disc 21 is of a substantial weight so that its eccentric mounting endows it with amply sufiicient power to actuate th catch-operating mechanism by its ably triangular, providing inclined surfaces 33*;

3 for cooperation with the crank-pin 32 so as to enable the latter to exercise a levering'action on the toggle lever 26' and thereby actuate the samewh'en the disc 21 is rocked. I I I What I 01am as my invention" and desire to secure by Letters Patentis I I I I 1: A bobbinsuspensory attachment' compri' sin g an elongated member adapted for attachment to a creel at one endand for insertion into the hollow bore of a bobbin'at the other end; a tumbler member pivotally mounted on said elongated member so as to be impinged upon-and rocked about its pivot by the bobbin when the-latter is moved upwardly on said elongated member above the position in which it is ordinarily retained, a catch member pivotally mounted on saidelongated member and having a bobbin-retaining position and an inoperative position, a'le'ver:pivot'ally mounted on said elongated member and capable of 'movement to turn the catchmembfer from its bobbin retaining position to its ino'pei' a'tive position and vice versa, and a connection between said tumbler member and said lever for moving the lever in response to a rocking move ment of the tumbler.

rotatable disc mounted eccentrically with respect to its pivot, so that when impinged upon by the bobbin the disc is tumbled over its eccentric pivot axis and thereby throws the said lever to turn the catch member.
